Abstract

The present invention relates to a tin-containing and/or bismuth-containing zinc alloy for hot galvanizing steel, more particularly for steel component galvanizing. The alloy is composed of 1 to 5 percent by weight of tin and bismuth, 0 to saturation of lead, 0.025 to 0.200 percent by weight of at least one metal being selected from the group consisting of nickel, chromium or manganese, 0 to 0.030 percent by weight of at least one metal being selected from the group consisting of aluminium, calcium and magnesium, the remainder being zinc and unavoidable impurities. Disclosed is also a process for hot dip galvanizing of steel components, in which the components to be galvanized are dipped in a bath performed from the above-described alloy.

Description

Slitina a způsob zinkování oceli ponoremAlloy and method of hot dip galvanizing of steel

Oblast technikyTechnical field

Vynález se tyká slitiny zinku obsahující cín a bismut, určené pro zinkování ocele ponorem do roztaveného zinku a zejména zinkování ponorem ocelových dílů.The present invention relates to a zinc alloy containing tin and bismuth, intended for hot dip galvanizing of steel into molten zinc and in particular hot dip galvanizing of steel parts.

Dosavadní stav technikyBACKGROUND OF THE INVENTION

Vliv přídavku pouze cínu a přídavku cínu a niklu do zinkové lázně je diskutován v patentovém dokumentu EP 96200465.1. Tyto přídavky zajišťují zpoždění reakce Zn/Fe v případě reaktivních ocelí, jakými jsou ocele obsahující křemík nebo/a fosfor. Tímto opatřením se zabrání vytvoření příliš silných vrstev zinku. Aby se toho dosáhlo, je však zapotřebí relativně vysoké koncentrace cínu v lázni, což činí tento způsob zinkování ponorem málo ekonomicky přitažlivým. Kromě toho je zde při značně vysoké koncentraci cínu v lázni nebezpečí tvorby heterogenní galvanizační vrstvy obsahující sraženiny cínu.The effect of the addition of only tin and addition of tin and nickel to the zinc bath is discussed in patent document EP 96200465.1. These additions delay the reaction of Zn / Fe in the case of reactive steels such as silicon and / or phosphorus containing steels. This prevents the formation of too thick layers of zinc. In order to achieve this, however, a relatively high tin concentration in the bath is required, which makes the hot dip galvanizing method less economically attractive. Furthermore, there is a danger of forming a heterogeneous galvanizing layer containing tin precipitates at a very high tin concentration in the bath.

Účinek vanadu, chrómu, niklu a manganu na reakci Zn/Fe je popsán v: J. J. Sebisty a kol., Proceedings of the 8th Intemational Conference on Hot-Dip Galvanizing, Londýn, 1967. Tyto slitiny jsou vsak nedostatečně účinné pro přesné zinkování ocele obsahující fosfor nebo ocele mající vysoký obsah křemíku.The effect of vanadium, chromium, nickel, and manganese on the Zn / Fe reaction is described in: JJ Sebisty et al. phosphorus or steel having a high silicon content.

Cílem vynálezu je omezit koncentraci cínu v zinkové lázni, neboť cín je poměrně drahý kov, při zachování schopnosti lázně dosáhnout přesného zinkování ocelí obsahujících fosfor a ocelí majících vysoký obsah křemíku.It is an object of the invention to limit the concentration of tin in the zinc bath, since tin is a relatively expensive metal, while maintaining the bath's ability to achieve accurate zinc plating of steels containing phosphorus and steels having a high silicon content.

Podstata vynálezuSUMMARY OF THE INVENTION

Výše uvedeného cíle se podle vynálezu dosáhne tím, že se použije slitina zinku obsahující celkem 1 až 5 % hmotn. cínu a bismutu, 0 až saturační koncentraci olova, 0,025 až 0,200 % hmotn. alespoň jednoho kovu z množiny zahrnující nikl, chrom a mangan a 0 až 0,30 % hmotn. alespoň jednoho kovu z množiny zahrnující hliník, vápník a hořčík, přičemž zbytek je tvořen zinkem a neodstranitelnými nečistotami.The above object is achieved according to the invention by using a zinc alloy containing a total of 1 to 5 wt. tin and bismuth, 0 to saturation concentration of lead, 0.025 to 0.200 wt. % of at least one metal from the group comprising nickel, chromium and manganese; at least one metal of aluminum, calcium and magnesium, the remainder being zinc and non-removable impurities.

V závislosti na situaci na trhuje možné nahradit cín částečně bismutem. Olovo může být přidáno až do nasyceného stavu. Olovo je lacinější než cín a bismut, avšak je méně účinné a méně přitažlivé z ekologického hlediska.Depending on the market situation, it is possible to replace tin partly with bismuth. The lead can be added to the saturated state. Lead is cheaper than tin and bismuth, but is less effective and less environmentally attractive.

V důsledku přidání cínu a bismutu do zinkové lázně se zlepší smáčivost povrchu ocele určené k zinkování a současně se sníží teplota tání zinkové lázně. To má za následek celou řadu výhod, mezi které patří například možnost provádění zinkování při nižší teplotě, čímž se zase sníží spotřeba energie a omezí korozivní schopnost zinkové lázně. Rovněž je možné použít krátké časy ponoření ocele do zinkové lázně a mohou být rovněž získány extra tenké vrstvy zinku na povrchu ocele.As a result of the addition of tin and bismuth to the zinc bath, the wettability of the surface of the steel to be galvanized is improved while the melting point of the zinc bath is lowered. This results in a number of advantages, including for example the possibility of performing a lower temperature zinc coating, which in turn reduces the energy consumption and reduces the corrosive ability of the zinc bath. It is also possible to use short immersion times of the steel in the zinc bath and extra thin zinc layers on the steel surface can also be obtained.
